Abstract

Objective: The prevalence of type 2 diabetes mellitus escalates with aging although β-cell mass, a primary parameter of β-cell function, is subject to compensatory regulation. So far it is unclear whether the proliferative capacity of pancreatic islets is restricted by senescence. Materials and methods: Human pancreatic tissue from n=20 non-diabetic organ donors with a mean age of 50.2±3.5 years (range 7–66 years) and mean body mass index of 25.7±0.9 kg/m 2 (17.2–33.1 kg/m 2) was morphometrically analyzed to determine β-cell volume, β-cell replication, β-cell apoptosis, islet neogenesis, and pancreatic duodenal homeobox-1 (PDX-1) expression. Results: Relative β-cell volume in human pancreata (mean 2.3±0.2%) remains constant with aging (r=0.26, P=ns). β-cell replication (r=0.71, P=0.0004) decreases age-dependently, while β-cell apoptosis does not change significantly (r=0.42, P=0.08). Concomitantly, PDX-1 expression is downregulated with age in human pancreatic tissue (r=0.65, P=0.002). The rate of islet neogenesis is not affected by aging (r=0.13, P=ns). Conclusions: In non-diabetic humans, aging is linked with impaired islet turnover possibly due to reduced PDX-1 expression. As β-cell replication is considered to be the main mechanism responsible for β-cell regeneration, these changes restrict the flexibility of the aging human pancreas to adapt to changing demands for insulin secretion and increase the risk for the development of diabetes mellitus in older subjects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
